I have tried using VISS for over a year and it locks up my desktop using WinXP 32 bit and I.E. I had to remove it and use a freebie Avast which allows the system to operate correctly. I also had to do the same with my laptop (VISTA 32)as the lock ups caused me to use a hard reset. I noticed that the systems operated correctly before Verizon changed the system with an upgrade, and after that, the system started locking up. I am still paying Verizon for the service, but am on the verge of canceling.
By the way, I tried installing VISS on Win7 beta, but it would not go.
One other thing, if you have any vestiges (orphan files) of any other virus checker on the machine, VISS will not install correctly. You have to remove all virus checkers and in some cases search through the registry for those reminants of files the installer does not remove.
I honestly think that my problem is because I have some orphan files that VISS interacts with causing my lockups. I have vigerously searched and reinstalled VISS, but it still causes lockups. I am tired of a program that acts that badly. I have tried e-mailing Verizon for an answer but all I get back is a reference to a FAQ that does not answer anything. I hope a moderator has some suggestions as I would like to keep the service without the lockups.
